Ap'piicafionmed necemter 20,1915.l ,seriaiiesavaz l To all whom t may concern.'

Be it known that I, STANLEY- resident of San Jose, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Pump Mechanism, of which the following is y' 16. Atany desirable distance above bowl 4 a. specification.

My invention relates to pump mechanism,

and more particularly to shaft bearings and parts connectedthereto. Two of the greatest diflicultiesinvolved in the operation of driving a shaft coupled to a pump submerged in a well, are the keeping of the bearings of said shaft properly lubricated and securing a more perfect and rigid alinementV of said shaft. It is the object of this invention to overcome the above named difficulties as well as to simplify the construction and operation of the mechanism and to reduce the installation cost by eliminating 'certain portions rendered .unnecessary by my special form of construction. Other obgects are to prolong the life of the mechanism, and to provide a simplel and effective Cooling system for the same.

These objects are obtained .by means of the mechanism described and claimed in this specification and illustrated in the accom- Fig. 2 is a vertical section through the lower bearing.

Fig. 3 is a sectional view on line A-A of Fig. 2.

Similar characters of reference refer to similar parts throughout thei several views.

Referring now more particularly to the drawings, 1 indicates the well casing and 2 the discharge head secured to casing 1 by bolts 3. At 4 is indicated a pump bowl secured to discharge casing 9b by bolts 6, the shaft 7 being secured toV pump 5 in bowl 4 and driven in any practical manner. 'Shaft 7 passes through conduits as S and 8a, the discharge casing sections being shown at 9, 9a, etc. The uppermost bearing for shaft 7 is located in the discharge head at 10. part 10 being preferably cast integral with the discharge head 2 and threaded interior-lv to receive bearing 11. Bearing 11 is provided 'with a cup shaped tcp surface as lindicated shown,.and the amount of oil fed. is regulatedv by a. valve 14 or by any other suitable regulator.y The lower end of bearing 11 is tapered slightlyv as shown "at`15 in order to receive the upperfendof conduit 8, said conduit end slippinginto'part 10 as shown, at.

is positioned bearing 17, the saine being interiorly threaded at each end as shown at 18 which' is uconnected to a sou-rceof supply not M. HAL- s'rnAD, a citizen of the United States, andy and 19 lrespectively to receive the threaded ends of discharge pipe sections 9a andI 9 respectively, shoulders 20 and 21 being made parallel and true softhat when the ends'o'f` -the discharge casings are fitted to said bearings said .caslngs will be inperfect aline-f ment. At 22 is indicated .the babbittedv ortion of the bearing in the hub 23, said hu '23 fbeing connected to the outer wall of the bearing by webs as 24. The upper ed e of v.hub 23 is providedwith .anannular rab et as v25, thusforniing a seat 26, said rabbet 25. and seat 26 serving to receive one end of la conduit as 8a. At 27 is shown an annulanehannel cut into, or out of, babbitt 22 and drained by auxiliary. conduits 28 passing through webs 24 to the outside and discharging into the well proper.

The above description covers the"- special construction of the top ,and bottom'bearings. The intermediate bearings are` made similar to the bottom bearing` lastv described, with the exception that .they are not provided with the annular channel 2,7 and auxiliary conduits? 28 and are piovidedwith a rabbet as 29 and seat 30 on the lower edge of the hub portion as shown'in Fig. 1. Y.

Vhen the parts arebeingprepared for assembling, the `ends 'of the discharge-'casing. sections are manipulated in a lathe lin such a manner as to' be threaded exactly the. same and to have their ends parallel and true, so

that when screwed into the threaded portion l of the l eaiing. as section 9a into bearing 17 at 1S. the section ivill come to a truev seat.

as at 20. ,y By bringing each discharge casing l section to an exact and true seatasabove described. the successive sections must be 1n alincment.l and being screwedin tight must provide' afverlv rigid andsecure discharge casing. Since the hub of each bearing meme.;

It is of course well anown 'that clear Water isjen excellent lubricant but the teni eney oi' the shaft to corrode renders its use obiectionoble when used alone.' The use of oi? r :tiene is highly objectionable as it conyterminetes.the Water to suoli :1 degree as to become a, nuisance when fed from the, top or bottom, and requires e more or less complicated system of pipes when fed directly to each bearing besides adding considerably to 'the expense of operating. l obvmte these objectionable features by using 'am oil. emulsion :is al lubricant as :ibo .ler described, thereb lrovidimr le cheep lubricating medium a 1 y a preventing corrosion ot the sl e. not conterminating the Water lelivere and, on ecconnt of the Aconstant'flow of Water through the bearings,.providing an elicient cooling system for snidbearings.

It will be readily seen, of course, that since the conduits are connectcrl to the 'Well proper by channel 27 :1md auxiliary conclnits 28 the Water in seid conduits will be @"lrainedl t0 the level of the Water in the Well when the .pump is in' operation, ond conseqnently there will always be a movement of the Water into said conduits, down Atbe it through The draining (luces to economy by obvieting tbe \-:f^eity Lllt should be unclerstoorl t let Specifically describe? n emit:
